Abstract
A telephone line driven power supply and power supply method capable of creating high yield, low voltage power using power drawn from a telephone line and supplementing the low voltage power with power from a battery-powered host device, such as a laptop PC, when the voltage level falls below a predetermined voltage level. The telephone line power supply includes a polarity guard, a gyrator, an oscillator, a pulse circuit, an inductor, a startup circuit, a converter, a shunt regulator, and a combiner circuit. The method includes supplying line power from power drawn from a telephone line, receiving host power from a host device, supplying the line power to an electrical device, and supplementing the line power with the host power when the voltage level of the line power falls below a predetermined level.
